4. Approach Input Video Clip Separate Individual Frames & Find Background
Separate Foreground from Background in each Frame
Filter Out Points With Threshold
Imdilate Points To Improve Picture
Overlay Each Foreground On Background To Create Individual Frame
Combine Frames Into Video Clip

5. Matlab Stuff
Frame - Background
BWareaopen
Imdilate

6. Observations
Had to play with thresholds depending on background and foreground object seemed to work best for “difference”.
For Bwareaopen, 4 seemed to be sufficient.
For imdilate, I used 5 to get enough coverage area.
I used every 5th frame to make the matlab processing run in a reasonable time.

Usually on TV they just switch camera angles...now wouldn't it be cool if we had the whole view?
